Решение

1) 16-29+14-48=16+14-29-48=30-29-48=1-48=-47

2) -3,2-7,8-5,4+4,6= - 11 - 0,8 = - 11,8

3) -4,28-1,53-(-7,85)+(-9,06)= -4,28 - 1,53 + 7,85 - 9,06 = -7,02

[tex]4) -5\frac{3}{8}+4\frac{5}{6}-(-2\frac{1}{4} )=-5\frac{3}{8} +2\frac{2}{8} +4\frac{5}{6} =-3\frac{1}{8}+4\frac{5}{6}=1+\frac{5}{6}-\frac{1}{8} =1+\frac{20-3}{24} =1\frac{17}{24}[/tex]

[tex]5)-3\frac{3}{5} +(-2\frac{1}{3})+4\frac{8}{15} -1\frac{5}{6} -(-6\frac{7}{10})+\frac{1}{2} =(-3\frac{9}{15}+4\frac{8}{15} )-(2\frac{2}{6} +1\frac{5}{6} )+6\frac{7}{10} +\frac{5}{10}=\\ \\=\frac{14}{15} -4\frac{1}{6} +7\frac{2}{10}=3+\frac{14*2-5+2*3}{30} =3+\frac{28-5+6}{30} =3\frac{29}{30}[/tex]
